Application filed September 11, 1899. Serial No. 730 1241 (llo modeld To lbl li III/M11721 it may IIHIMt/Jll'b:

Be it known that I, 'luoams Arri'u'rnin, a citizen oi the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Illl' proveinents in ater-Supply Apparatus for Buildings, of which the 'lollowing is a full,

clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a water-supply apparatus'for use in buildings, the object of the invention being to utilize the reactionary force or concussion created in the apparatus, known as water-hammer, to raise the Watcr through the pipes to an elevation therein and store it in a tank forming a part of the apparatus.

it is a Well-known fact that in the watersupply apparatus of buildings where thespparatuspipes are carried to any considerable height it is impossible to at all times maintain a continuous supply of water at the upper end of the apparatus owing to the fact that there does not exist sufficient pressure to automatically carry the Water to the great est elevation when the pressure is reduced by reason of water being withdrawn from the supply or conveying pipes.

In the apparatus which I have devised I provide for the maintenance of a constant supply of water at the greatest elevation of the apparatus, as will be hereinafter shown.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a view in elevation of myimproved apparatus applied to a building. Fig. II is an enlarged vertical sectional view of the reservoir-tank with which the apparatus is equipped, the pipes and valves connected thereto being shown in elevation.

1 designates the main water-supply pipe, leading into the building from a source of L pply and provided with a shut-oil valve 2.

- designates branch, pipes loading from the supply-pipe l and provided with cooks or faucets 4;. Located at intervals in the supply-pipe 1 are check-valves and 5", that permit the inflow of water through said pipe,

hut prevent retrograde llow thereof. The

pipe 1 is also provided with shut-oil val vcs 5 and T, and said pipe ads to a rescrvoir-tank 8, locaied on one of the upper iloors oi the ed to the supply-pip? 1. intermediate vof the locations of the valves 3 and 7 in said main supply-pipe. The branch pipes are provided with shut-oil valves 10 and cooks or faucets ll, through which water may be drawn to supply the needs or" the upper floors of the building.

12 designates a Waste-pipe to which the usual trap-pipes 13 lead from sinks 1 orother receptacles into which the Water isdischarged from the cocks or faucets i and 11.

15 is a vent-pipe provided with connectingpipes 16, leading to the trap-pipes i3.

17 designates a drain-pipe provided with a valve 13 and loading from the main supplypipe 1 from a point between the valves 6 and 7 to the waste-pipe 15. This drain-pipe 17 is designed for service in draining the water from the reservoir-tank 8 for the purpose oi.-

clean sing or repairing.

l!) designates a pressure-exhaust pipe leading from the drain-pipc l7 and having an open end This pressure-exhaust pipe is provided with a pressure-check valve 21, adapted to retain water therein at a limited degree of pressure, but subject to being overcome by a high. pressure of water when the water may how to the open end 330 of said pipe to relieve the high degree of pressure and avoid danger to the pipes or tank of the apparatus is liable to client a wear upon the valve-seats and to cause a leakage, and by using a second upper valve any leakage that results past the lirstvalvc is stopped by the second.

:25 is a cap that incicses the end of the pipe to exclude dirt therefrom.

v In 'ihc practical use 05 this :ipparatus the eencussien or waiver-hammer resulting from ihe opening closing-pf the cocks through out the pipe 1 in drawing Water therefrom for is therefore stored in the reservoir-tank to be drawn therefrom into the branch sup" ply-pipes 9 and forced upwardly therein under the action of air-compression in the reservoir-$215k above the Water tiiei'ei 11" The device prevides for a'consisant supply ofiimter on the upper floors ef the building; to which Who WatBi' would otherwise not flow o itingto insufficient pressure in the water-supply.

The apparatus is of marked utility in con nection with stills; and watenfiitei-s whereit is desirable to main Lain a. consi'anb supply ofv Water in order to permit a continuous opera,- tion of the stiii or fiitei'.
